A lighter, more wearable Fahrenheit...
Aqua Fahrenheit is a new take on the original Fahrenheit, with a concept of "fire meets water", hence the "Aqua" prefix.
To me, I think this is a lighter, summer version of the original, a kind of "Eau de Fahrenheit" almost. It has a huge citrus note, provided by grapefruit, and this stays throughout the life of the fragrance, only drying down to original Fahrenheit at the end. You still get the violet leaf/leather (ie the "petrol" note) combination in the background, but the top and middle of the fragrance is dominated by the Grapefruit and Mandarin. I also get the mint and herbs, which combine with the citrus to give it a fresh feeling.
If I had to give it a name, I would call it Fahrenheit "fresh", because if you found the original stuffy and "too much", then give this one a try. It's a great clean, citrus take on the original "dark" and "heavy" Fahrenheit, and it can be worn all year round in my opinion. New, original take on a classic from Dior. Really good stuff.
